Humans

Vulcans

Romulans

Klingons

Cardassians

Which species in Star Trek seems to be advancing fastest? I think given the short amount of time it took Humans to advance to the point of warp capability that they are advancing faster than the others.

Humans by far, all the others are established to have already been space faring when humans first set out. Except Cardassians, but vague references to their past seem to point to more than 300 years ago.

They all seem pretty stagnant to me. Human ships are pretty much the same, except the warpometer goes up to 9.975 instead of 5, and they have holodecks which they seemingly got from the Xyrillians. The Klingons were flying the same ships in Enterprise as they were in Deep Space Nine, almost 250 years later. It seems you get into space and then... everything pretty much stays the same

In fact, it looks like Vulcans have severely stagnated. They "redeveloped" space travel in Earth's 19th century and were tooling around the galaxy at warp well before humans were. In fact, Vulcans tried to limit human warp development and space exploration in the 22nd century. By the 23rd and 24th centuries humanity has developed to a tech level equal to Vulcans; or so it seems.

It's all about point of view, from what we saw in the shows id think they're all pretty much equal.
If you consider the First episode you see the Ferengi they seem pretty primitive, sorta make you think of cavemen, and then they have ships, tailored clothing and their you're typical business man.

But if Id put money on a Race it would be the Founders. They basically conquer other races, probably "assimilating" their Technologie, and what not. They can clone,... so, yeah.

I would have like a few more choices in this poll, but no worries. The results, I think would be the same. In the end, the show focuses on the Federation and our progress over the decades of Trek. Yes, we've seen progress in the other species, but given the human focus of the show, it's natural that our progress is front and center. How many wars have we fought, how many ship classes have we seen, and how many uniform changes have we endured compared to other species...

After all, they're all like astronauts on some kind of star trek. (Couldn't resist...)
